What are the 3 angles of a right triangle?
There can be many different angles of a right triangle. One must, however, be 90o ---- They are called Leg A, Leg B, and the Hypotenuse , if it was what you were asking
I have a right angled triangle which i know all the angles of. I have the length of one side which is adjacent to the right angle. How can I work out the length of the hypotenuse and the other side?
Use tangent to find the other leg, and the sine or cosine to find the hypotenuse.
How do you find the base leg of a right triangle if you know the hypotenuse and one acute angle?
By using trigonometry that is applicable to a right angle triangle.
What are four ways you can prove two right triangles are congruent?
1. The side angle side theorem, when used for right triangles is often called the leg leg theorem. it says if two legs of a right triangle are congruent to two legs of another right triangle, then the triangles are congruent. Now if you want to think of it as SAS, just remember both angles are right angles so you need only look at the legs.2. The next is the The Leg-Acute Angle Theorem which states if a leg and an acute angle of one right triangle are congruent to the corresponding parts of another right triangle, the two right triangles are congruent. This is the same as angle side angle for a general triangle. Just use the right angle as one of the angles, the leg and then the acute angle.3. The Hypotenuse-Acute Angle Theorem is the third way to prove 2 right triangles are congruent. This one is equivalent to AAS or angle angle side. This theorem says if the hypotenuse and an acute angle of a right triangle are congruent to the hypotenuse and an acute angle of another right triangle, the two triangles are congruent. This is the same as AAS again since you can use the right angle as the second angle in AAS.4. Last, but not least is Hypotenuse-Leg Postulate. Since it is NOT based on any other rules, this is a postulate and not a theorem. HL says if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.
If a right triangle has a hypotenuse of 12 cm and one leg that measures 9 cm find the length of the other leg.?
Using Pythagoras' theorem for a right angle triangle the other leg is 3 times the square root of 7

How do you find the short leg of a right triangle?
The answer depends on what information you do have about the triangle: the lengths of the other two sides, or the hypotenuse (longest side) and one of the acute angles, or the other leg and one of the acute angles, etc.
How do you find the angle of a right triangle with the length of two legs?
-- Like every triangle, a right triangle has three interior angles.-- Unlike any other triangle, one of the angles in a right triangle is a right angle.The other two are both acute angles.-- One acute angle is the angle whose cosine is length of one leg / length of hypotenuse-- Other acute angle is the angle whose sine is length of the same leg / length of the hypotenuse-- The length of the hypotenuse is the square root of [ (length of one leg)2 + length of other leg)2 ]
If one leg of triangle is 6 inches and the other leg is 78 inches what are the angles of the hypotenuse?
If one leg of triangle is 6 inches and the other leg is 78 inches, the angles are:4.399 degrees85.6 degrees
What are the 2 triangle congruence theorems?
The two triangle congruence theorems are the AAS(Angle-Angle-Side) and HL(Hypotenuse-Leg) congruence theorems. The AAS congruence theorem states that if two angles and a nonincluded side in one triangle are congruent to two angles and a nonincluded side in another triangle, the two triangles are congruent. In the HL congruence theorem, if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, the two triangles are congruent.
How do you find x in a right triangle?
That depends on what x is: a leg, an angle, what?
I have a right angled triangle which i know all the angles of. I have the length of one side which is adjacent to the right angle. How can I work out the length of the hypotenuse and the other side?
Use tangent to find the other leg, and the sine or cosine to find the hypotenuse.
Are right triangles sometimes scalene?
Yes, they can be. For example, if one leg of the triangle is 6 inches and the other leg is 8, then the hypotenuse would be 10 inches long by the pythagorean theorem, I believe. They can not be equilateral. They can, however, be isosceles. I hope that this helps!
What is Hypotenuse Leg?
If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.
How do you find the base leg of a right triangle if you know the hypotenuse and one acute angle?
By using trigonometry that is applicable to a right angle triangle.
Area of right triangle?
The area of a right triangle is dependent on the length of leg A and leg B. The formula for this is A= leg a multiplied by leg b then divided by 2.
